Description

Technical Field

[0001] This utility model mainly relates to the field of fixation lamp technology, specifically an ophthalmic examination fixation lamp. Background Technology

[0002] Ophthalmological examinations can assess eye function. Commonly used visual function tests include visual psychophysical tests (such as visual acuity, visual field, color vision, dark adaptation, stereopsis, and contrast sensitivity) and visual electrophysiological tests. Visual acuity and visual field tests require the examiner to use appropriate equipment.

[0003] During ophthalmological examinations, fixation lamps are required to examine patients. However, existing fixation lamps have limited installation options and cannot be fixed on supports with various cross-sections, resulting in poor adaptability. Utility Model Content

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] An ophthalmic examination fixation lamp includes a base and a power cord. A stainless steel corrugated tube is fixedly installed at the center of the top of the base, and a lamp body is fixedly installed at the end of the stainless steel corrugated tube. The power cord passes through the stainless steel corrugated tube and communicates with the lamp body. A first groove is formed at the bottom of the base, and second grooves are symmetrically formed on both sides of the first groove at the bottom of the base. A fixing plate is provided at the bottom of the first groove, and a pad is provided inside each of the second grooves.

[0006] Both the first groove and the fixing plate are arc-shaped. The four corners of the top of the fixing plate are fixed with first screws. The first screws pass through the base. Each first screw has a butterfly nut threaded onto its outer ring. The butterfly nut abuts against the top of the base.

[0007] The side of the fixing plate is rotatably connected to the second screw, which passes through the second groove and has a knob fixedly installed at its end.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This utility model has a simple structure, is easy to disassemble and install, and meets the needs of examination. By using a stainless steel corrugated tube, it is convenient for medical staff to adjust the fixation position and the operation is quick. The first groove, when used with the fixing plate, can fix the device on the surface of the cylindrical support. The second groove, when used with the pad, can fix the device on the surface of the rectangular support, thereby improving the adaptability of the device. Attached Figure Description

[0014] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0015] Referring to the accompanying drawings, an ophthalmic examination fixation lamp includes a base 1 and a power cord 8. A stainless steel corrugated tube 2 is fixedly installed at the center of the top of the base 1, and a lamp body 3 is fixedly installed at the end of the stainless steel corrugated tube 2. This structural design allows the lamp body 3 to be adjusted and shaped in all directions. The power cord 8 passes through the stainless steel corrugated tube 2 and communicates with the lamp body 3. A first groove 4 is provided at the bottom of the base 1, and second grooves 5 are symmetrically provided on both sides of the first groove 4 at the bottom of the base 1. A fixing plate 6 is provided at the bottom of the first groove 4, and a pad 7 is provided inside each of the second grooves 5.

[0016] The first groove 4 and the fixing plate 6 are both arc-shaped. The four corners of the top of the fixing plate 6 are fixed with first screws. The first screws pass through the base 1. Each first screw is threaded with a butterfly nut 9 on its outer ring. The butterfly nut 9 abuts against the top of the base 1. The spacing of the fixing plates 6 is adjusted by tightening the butterfly nuts 9 to fix the base 1.

[0017] The second screw is rotatably connected to the side of the fixing plate 6. The second screw passes through the second groove 5 and a knob 10 is fixedly installed at its end.

[0018] When the device is fixed on a cylindrical bracket, the first groove 4 and the inner ring of the fixing plate 6 abut against the outer ring of the cylindrical bracket, and the device is fixed by tightening the butterfly nut 9. When the device is fixed on a rectangular bracket, the fixing plate 6 is removed, the base 1 is placed on the rectangular bracket, and the knob 10 is rotated to move the pad 7 so that it abuts tightly against the rectangular bracket to achieve fixation.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
